摘    要:Although numerous papers have been published on nutrients in Great Lakes, estuaries, continental shelf areas and marines in the aspects of determination, sediment-water-interface exchange, fluxes and budget estimation, eutrophication and microbial processes as well as modeling study, the knowledge of river condition (especially urban river) is uncertain and simply considered as a contributor to eutrophication of estuary. After a series of determinations of nitrogen species corresponding to ammonia-N (AN), Kjeldahl-N (K-N), and total nitrogen (TN) by means of National Standards for China, the nitrate & nitrite (Nitr-N) and org-N were obtained by the difference of TN with K-N, and K-N with AN, respectively. Therefore, the behaviors of vertical distributions in overlying waters and porewaters in the Fu and Nan Rivers located in Chengdu City were achieved.
